Abstract

A method of operating an internal combustion engine (12) in an agricultural harvester (10) includes the steps of operating the engine (12) in a normal mode with a base torque curve (42) as a function of engine operating speed and engine power output, the base torque curve (42) being generally isochronous at a rated operating speed over a power output range terminating at a rated power output; and operating the engine (12) in a boost mode with a boost torque curve (48) when a power boost is required above the rated power output, the boost torque curve (48) having a power output which is above the base torque curve over a predefined range of the operating speed.
